Thanks for pointing out this information, Brian.  I want to clarify,
though, that registration is _not_ required to use WWW-Entrez, although
it is required for Network Entrez.  Information regarding both of these
services, as well as the Entrez CD-ROM is available by following the
"Entrez Browser" hypertext link from the above WWW page.

Information about Network Entrez is also available by viewing the file
ftp://ncbi.nlm.nih.gov/entrez/network/README or by writing to
net-info at ncbi.nlm.nih.gov.
